The organism must be buried quickly. For this to happen, the organism normally must die in abnormal
conditions such as in a flood, volcano eruption or an earthquake.
Otherwise it is near impossible for an animal to be preserved;

The organism must be kept from normal decay. If the animal is exposed to
oxygen or bacteria, they will quickly start to decay;

The organism must be buried in matter that is leached with mineral-rich
waters where carbonates are precipitating. These minerals will replace the original tissue, so that a
stone remains in the shape of the original tissue.

It is interesting that about 75 percent of all the continental area surfaces are covered with sedimentary
72
rock. Yet it composes only about 5% of the total rock mass of the earth. Almost all the sedimentary
soil or rock covers a thin layer over the outer surface of the surface of the earth, exactly as we would
73
imagine if there was a world-wide flood 4,000 years ago! The evidence is so obvious --- even a blind
person can see that the world was covered with water. Here are some types of sedimentary rock:

Sandstone Limestone Clastic rock Conglomerate Carbonate rock Arkose

All sedimentary rocks are carbonate rocks. They consist of 50 percent or more calcite and aragonite.
